Multi-Parameter Vital Sign Telemedicine System Using Web Socket for COVID-19 Pandemics

Area of Science:

• Biomedical Engineering
• Health Informatics
• Telecommunications

Background:

• Telemedicine is crucial in modern healthcare, amplified by the COVID-19 pandemic.
• Existing cloud platforms present limitations for real-time vital sign monitoring in telemedicine.
• Real-time application monitoring for vital signs is a significant challenge in current telemedicine systems.

Purpose of the Study:

• To develop and evaluate a web-based telemedicine system for real-time monitoring of six vital sign parameters.
• To address the limitations of commercial platforms for time-sensitive telemedicine applications.
• To investigate the feasibility of using Web Socket technology for low-latency vital sign data transmission.

Main Methods:

• Designed a web-based application leveraging Web Socket technology.
• Implemented real-time monitoring for six vital sign parameters: ECG, temperature, plethysmogram, SpO2, blood pressure, and heart rate.
• Encoded vital sign data on a web server and decoded it on a client site upon login.

Main Results:

• Successfully remotely monitored six vital sign parameters in real-time.
• Achieved a latency of less than 5 milliseconds over a 4G mobile network.
• Demonstrated the effectiveness of the proposed multi-parameter vital-sign telemedicine system.

Conclusions:

• The proposed Web Socket-based telemedicine system effectively enables real-time, multi-parameter vital sign monitoring.
• The system offers a viable alternative to commercial platforms for critical telemedicine applications requiring low latency.
• This technology holds promise for improving remote patient care and monitoring capabilities.
